Managing mild to moderate Class II malocclusion is a one of the common and major challenges to orthodontists. Class II discrepancies with mandibular deficiency during active growth are usually treated by myofunctional appliances. Fixed functional appliances evolved due to the noncompliance with conventional myofunctional appliances. This case report illustrates the efficiency of PowerScope in correction of skeletal Class II with mandibular deficiency in a patient aged 13 years who has reported to the department with a chief complaint of forwardly placed upper front teeth. This case with functional jaw retrusion was treated initially with MBT 0.022" prescription followed by PowerScope. Pre-, mid- and post-treatment cephalograms were obtained, and cephalometric analysis was performed. Stable and successful results were obtained with a substantial improvement in facial profile, skeletal jaw relationship, and overall esthetic appearance of the patient. A significant forward displacement of the mandible was the principal element for successful correction of Class II malocclusion. PowerScope provides the best results for Class II management, thus enables us to treat such cases by a nonextraction approach rather than contemplating extractions.
管理轻度至中度II类错牙合畸形是正畸医生常见且主要的挑战之一。在生长活跃期伴有下颌后缩的II类牙合差异通常采用肌功能矫治器进行治疗。由于患者对传统肌功能矫治器依从性差,固定功能矫治器应运而生。本病例报告展示了PowerScope矫治器在一名13岁患者中矫治伴有下颌后缩的骨性II类错牙合畸形的有效性,该患者因上前牙前突为主诉前来就诊。该伴有功能性下颌后缩的病例最初采用MBT 0.022英寸矫治方案治疗,随后使用PowerScope矫治器。治疗前、治疗中期和治疗后均拍摄了头颅侧位片,并进行了头影测量分析。获得了稳定且成功的治疗效果,患者的面部轮廓、骨骼颌骨关系以及整体美观度都有了显著改善。下颌的明显前移位是成功矫治II类错牙合畸形的主要因素。PowerScope矫治器为II类错牙合畸形的治疗提供了最佳效果,从而使我们能够通过非拔牙方法治疗此类病例,而非考虑拔牙。
